Laim Patent No. 96,767, dma November 16, 1869.

IMPROVEMENT 1N EAR-racer.'czssrrs The Schedule referred to in theseLetters Patent and making part ol'- the same To all whom it may conce-rnBe it known that I, AUGUSTUS FRASER BAIRD, of Pimlico, in the county ofMiddlesex, England, have inventedanew and useful Improvement in Earth-Closets and Urinals; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art'to make and use the same, reference being had to theaccompanying drawings, forming part ot" this specification.

The nature of this invention consists in constructing an earth-closet,which is provided with a receptacle beneath the seat, for receiving thedeposits with whichl the earth is to be mixed, and with' a chute orpassage, opening into the said receptacle, for conveyf ing the earthinto the same, and at the other end, to that opening above mentioned,another opening, by which the earth is supplied from a hopper to thesaid chute.

The bottom of' this'hopper is curved, and provided with thelast-mentioned opening for communication with the chute, and is openedand closed by the act-ion of a sector-piece, or other valve weighted asa counterbalance. This Valve is secured to and forms part of a tiap orvalve hung. at the centre, the otlice of which flap or valve is to closethe opening from the chute into the receptacle rst herein mentioned, thesame being effected by means Vof a projection from the cen- .tre of'thesaid ap or valve, situated just beneath the seat of the closet, so thatwhen at rest, the sectorvalve closes the entrance from the hopper to thechute, and prevents the discharge of earth into the said chute, while,when the closet is used, the weight of the sitter presses the seat`on`the said projection, and thus gives motion to the valve-arrangement,and opens the entrance from the hopper to the chute, shutting,r theentrance to the receptacle for deposits, thus causing the chute to belled up with earth, which is to be discharged therefrom into thereceptacle, by the removal of pressure, when the sitter gets up from theseat.

lrhe sector-valve has a rod or rods attached to it, working in thehopper, to prevent .the consolidation of the earth, and to cause it tomove as required.

Instead ofthe seat effecting the desired action, by the above-describedarrangements, there may be a ledge behind, or by the side ot' the seat,which may be acted upon by the push-down action of the seat, or by ahandle-action on the fore end of the valvearrangement, 4the chute beingat angle nearer a holizontal line than the above described. A hingedcover may also be adapted to the action, or'the action may be effectedby the intervention ofa connecter or cord, or wire, and handle.

Or, in lieu of the above-described arrangements, I can adopt thefollowing arrangements; that is to say, a hopper for supplying the earthto a chute or valve or {lap-box, and a Weighted Hap or valve workingtherein, are provided, whereby the deodorizing-earth is supplied tothereceptacles for excrementitious deposits.

For putting the "closet intoand ont of action, I make the weighted ap orvalve, which is to move on its pivots or axle, having bearings in thechute or valVe-boX, with its Weighted portion at a right or other anglevto the non-weighted portion, which latter has a part or projectionthereof or thereti'om, so curved vor formed that it shall act as a ap orvalve, for closing the entrance from the hopper at the same time thatthe weighted portion is leaving open the entrance from the chute orvalve-box to the receptacle for deposits.

By these arrangements, the valveor flap itself .can thus be pr'ovidedwith a cavity or portion, into which the dry earth'is received from thehopper, to be discharged by the action o'tlle mechanism' into the -re.

ceptacle for excrementitions deposits. They also serve to measure asufficient quantity of dry earth at each action.

At the angle at the back, although any other convenient position may beadopted, another smaller projection isprovided, so that by having a rodor rail attached to the seat of the closet, by means of side pieces orportions of the movable seat, the said seat will cause the flap or valveto open the hopper to the chute, and the chute to the receptacle fordeposits, as may be required.

Or, as above mentioned, the valve itself is rendered a moving chute ormeasure, for transferring from the hopper, by the action of themechanism, the proper quantity of dry earth to the receptacle fordeposits.

Instead ofY being actuated by the seat, the mechanism might be actuatedby a moving iooror by levers,

rods, or other gearing. For nrinals, arrangements of that characterwould, I consider, be found most suitable.

Should it be thonght necessary to agitate the earth, to preventclogging, an arrangement of levers or prongs can be attached to thecloset, so that the rising or falling of the weighted ap mayv act on thesaid arrangement of levers, in such a way as to agitate the earth.

In the accompanying drawings- Figure 1 represents a vertical section ofa chute or measure, showing' the opening to the reservoir opened and thechute closed, the dotted lines showing the opening to the reservoir shutoff and the chute or measure open.

Figure 2 is a section, showing a chute or measure open' to thereservoir, the casing in which the valve acts being curved in front.

Figure 3 is a sectionof the same, showing the opening closed.

Figure 4 is a section ofthe chute or measure without a casing, but,instead thereof, having sides above the weighted portion of the. valveitself. rlhis figure shows the chute or measure open to the reservoir.

Figure 5 is a section of the same, showing the chute or measure closedto the reservoir, and in the act of throwing the eartlrover deposit.

Figure 6 is a section of a closet with my invention applied thereto.

Figure 'l' is a section of a urinal with my invention applied thereto.

Similar letters of reference indicate corresponding parts.

A A is a chute, valve, or ilap, working on the pivots a, and weighted bya plate or valve, b

c is the curved projecting part of. the same;

l is a smaller projection, upon which rests a rod, r, acting inconnection with the seat ortloor of the closet, so that the valve isactuated by the raising and depressing of-the seat or door;

c is a guide-chute or trough; and

h denotes the hopper.

The shape of the casing in which thechute-valve acts need not terminatein a straight side, as in, tig. 1, but the curve may be continued, as ings. 2 and 3.

The capacity ofthe chute or measure of' earth may be also varied by theshape of the weighted portion of the valve, the upper surface e of whichmay bemore or less above the pivots a.

rIhe chute-valve or measure may also be formed without the use of acasing for the valve to work in, by putting sides above the weightedportion of th valve itself, as shown in figs. 4, 5,` 6, and 7.

The valve will only be hung on two supports, and willwork directly underthe opening of the hopper h.

There is also an arrangement by which a hinge chute-flap, e, for thechute, is provided, by hanging it to the end of the weighted portion ofthe valve, so that when the weight is lifted, by a person sitting down,(or by other means,) the hinge chute-flap hangs straight from the end ofthe weight, as in figs. 4, 5,

and 6, and when the weight falls, the hinge chute-.iiap is thrown into-aproper position to cast oi the earth into the pan or receptacle, as in'dgs. 5 and 7.

In iig. 6section of closet, and in iig. 7, section of urinal, S refersto the floor .or seat; H, the hinge or link, with which it is secured,but which allows it to be depressed bythe sitter, or otherwise raised bythe action of the weighted valve fr, the rod, above referred to, restingon smaller projection d, and actingin connection'with the seat or iloorthrough the lever L L.

P is the closet-pan or chute for urinal.

When the other arrangements firstly hereinbefore mentioned, which arenot illustrated by the drawings, are adopted, the top ofthe chiite is:of a curved form, corresponding With the curved form of the sector orweight-piece on the upper part of the Hap or valve, a. curved wire beingsecured to the weight-piece, and working in the dry earth in the hopper,(and care should-,be taken that the earth is dry when used in myearth-closets, as in other earthclosets,) which curved wire, so Working,as aforesaid, prevents it from consolidating, and secures its readydescent into the chute.

The bottom of the hopper is slanting, and the 'ap or valve has its edgesslightlybevelled,4 to diminish the fiietion.

The projection at the back of the iiap or valve, the depression of whichby the seat closes the valve, should be at the centre of the width ofthe ap or valve.

rBhe weight-piece should-be less in width .than the ap yor valve.

The wires or spikes may be two or three in number, and may be connected,at their upper ends, by a small bar.

An arrangement may be used for depressing the projection by means of theend of a hinged cover toV chute, aiding the earth in its exit, in caseof its being `-consolidated or hardened.

The lowering of the piece pulls down some prongs, moving on a pivot atthe top of the hopper or reservoir, causing the earth to move, so as toinsure its filling up the space emptied below, and preventing archingabove it. Thisy is all eii'ected by the weight of a person depressingthe seat. v

On the seat being released, a weight, attached to the upper prongs atthe back of the reservoir, brin gs all the prongs into their originalposition.

The upper and lower prongs are connected by a bar or chain.

The said upper prongs may be made to work at the sides, instead of theback,` the weight being inside, and there being two sets of prongs,instead of one, and two weights. v i

In another arrangement, I have the hopper anda movable chute, working onpivots, a weight-piece, a stop-piece, which may be also used as a chute,by being prolonged for that purp0se,and prongs, to prevent consolidationof earth. This arrangement can be put in action by the weight ofthesitter upon the seat, or by a handle, fastened to the pivot, vwhich mustbe lengthened for its reception. The handle can be used withthe otherapparatus.

. When the valve is brought from under the openingat the bottom ofthehopper, the chute is brought' overa piece provided, and its openingclosed, when the chute is filled with earth, .and upon the sitter`rising or letting the handle free., the weightedvalvefalls back andcloses the opening at the bottom of the hop per, and at the same time'opening the other opening, and the earth is free to cover the deposit.

The weighted valve, hereinbefore referred to, can be made wedge-shaped.

The chute or box, in which the earth is collected for use on eachoccasion, may be from three to six' inches wide, more or less, asdesired, so as to contain from one-half to three pints of earth.

The length from the centre to the top of the ap.

or valve of the chute or box, or from the centre of the lower endthereof, may vary according to circumstances, as may be found desirable.

lhe following arrangement, illustrated at iigs. 8, 9,

v 10, 11, and 12, may be adopted as a means for agitating the earth inthe hopper, to insure its dischargeas required.

Figure 8 is a side view of the said arrangement. Figure 9, a front viewof same. Figure l0, a plan of same.

Similar letters of reference indicate corresponding parts.

In figs. 1l and 19- l Z denote the agitator-arrangement, and

m fm, the flap-hoard, hereafter referred to.

Ihe other letters in figs. 11 and 12 denote similar .parts to thosereferred to by the same letters in n'gs. l, 2, 3, 4, 5, 6, and 7.

A light iron fraining n n, which should be of threeeighths-inch roundiron, with a piece of Wood, o o, fixed to one end, is hung in brackets pp, secured to the framing in front of the hopper.

Froma crossbair, g q, in the front part of the frame,

1 ises,it elevates this bar, which causes the wood at" the back of thehopper to strike the latter briskly. As the valve falls, the frame andstriker also fall, ready for another use. 4

Sometimes I use the flap-board m m, gs. 11 and 12, hinged at the'upperpai-toi` the back of the hopper,so that it will, when raised by thestriker o o, come sharply against the Whole of the back surface of thehopper, the flap-board corresponding in shape to the back of the hopper,and insure such an amount of vibration as cannot failto agitate theearth.

Having thus described my invention, l What I claim as new, and desire tosecure by Letters Patent, is-

The weighted chute-flap ox' valve A, arranged in earth-closets orurinals, in conjunction with a chutetrough, e, to operate substantiallyas herein shown and described.
